This models will display: Unitary signals → step, impulse, ramp Trigonometric signals → sine, cosine Exponential signals → growth & decay Operations → time shift, scaling, addition, multiplication

1. unitary_signals.py

Implements basic discrete-time signals:

• unit_step(n) – Generates a unit step signal.
• unit_impulse(n) – Generates a unit impulse signal.
• ramp_signal(n) – Generates a ramp signal.

2. trigonometric_signals.py

Implements continuous-time signals:

• sine_wave(A, f, phi, t) – Generates a sine wave with amplitude A, frequency f, phase phi, and time vector t.
• cosine_wave(A, f, phi, t) – Generates a cosine wave.
• exponential_signal(A, a, t) – Generates an exponential signal (growth/decay).

3. operations.py

Implements signal operations:

• time_shift(signal, n, k) – Shifts a signal by k units (delay/advance).
• time_scale(signal, n, k) – Scales a signal’s time axis by factor k.
• signal_addition(signal1, signal2) – Adds two signals element-wise.
• signal_multiplication(signal1, signal2) – Multiplies two signals element-wise.

4. main.py

Main script to demonstrate:

1. Generate and plot a unit step and unit impulse signal (length 20).
2. Generate a sine wave of amplitude 2, frequency 5 Hz, phase 0, over t = 0 to 1 sec.
3. Perform time shifting on the sine wave by +5 units and plot both original and shifted signals.
4. Perform addition of unit step and ramp signals.
5. Multiply a sine and cosine wave of same frequency and plot the result.
